[摘要]:The prepn. of new 3,6'- and 3,7'-biquinoline derivs. was achieved by microwave-assisted Suzuki cross-coupling between N-protected 6- or 7-bromoquinolin-2(1H)-ones and quinolin-3-ylboronate. Moreover, a new synthesis of 7-bromoquinolin-2(1H)-one leading solely to the 7-substituted isomer was carried out.
